Overview
The TSC2100IRHBR is a resistive touch screen controller and audio codec integrated circuit manufactured by Texas Instruments. It features a 12-bit resolution with sampling rates of 125 kS/s for touch and 48 kS/s for audio. The device operates on a supply voltage between 2.7 V and 3.6 V within an industrial temperature range of -40°C to +85°C. It supports multiple interfaces including SPI, I2S, and serial protocols. The component is housed in a VQFN-32 package and includes built-in headphone and speaker amplifiers.
Feature Summary
- Integrated 12-bit resistive touch screen controller with 125 kS/s sampling rate
- Stereo audio CODEC with 48 kS/s sampling rate and integrated headphone/speaker amplifiers
- Supports SPI, I2S, and serial interface protocols
- Operates within a 2.7 V to 3.6 V supply voltage range
Applications
- Portable multimedia devices requiring combined touch and audio functionality
- Industrial control panels with resistive touch interfaces
- Automotive infotainment systems
- Medical equipment with user input and audio feedback requirements
Procurement Notes
Verify the specific suffix IRHBR indicates the reel packaging format when ordering. Confirm that the VQFN-32 package dimensions match the target PCB footprint. Ensure the design supports the required SPI or I2S interface signals. Check humidity sensitivity handling requirements during assembly. Validate power supply constraints against the 2.7 V to 3.6 V operating range.
Selection Notes
Select this component when a single IC solution for both resistive touch input and stereo audio output is needed. Compare against standalone controllers if higher sampling rates or additional channels are required. Consider the VQFN-32 package size constraints relative to other TSC2100 variants like the IDA. Verify compatibility with the host processor's available serial interfaces.
Part Context
The TSC2100IRHBR belongs to the TSC2100 series from Texas Instruments. It shares core functionalities with variants such as the TSC2100IRHB and TSC2100IDA, differing primarily in packaging and reel specifications. This series integrates touch sensing and audio processing capabilities into a compact form factor suitable for space-constrained applications.
Replacement Considerations
Direct substitutes include TSC2100IRHB (tube packaging) and TSC2100IDA (TSSOP-32 package). Verify pinout compatibility and package dimensions before substitution. Ensure the alternative variant meets the same electrical specifications and interface requirements.
